        박은영(Eun-Young Park),박영호(Young-Ho Park) 한국콘텐츠학회 2009 한국콘텐츠학회논문지 Vol.9 No.4

        주 5일제의 영향은 여가시간 증가로 인한 가족 유대관계 향상이라는 결과를 가져왔다. 가족 간의 친밀함을 더욱 강화시킬 수 있는 다양한 방법들 중에서 놀이공원의 방문이 많이 애용되고 있으며 특히 공적공원의 관람은 저렴한 가격으로 서민들이 쉽게 찾을 수 있는 점 이외에도 다양한 장점을 가지고 있다. 이에 본 논문은 관람효과를 높이기 위한 방법의 일환인 사인디자인에 초점을 맞추어 연구하였다. 본 연구는 넓은 공간에서 동선을 고려하지 않은 안내표지판의 배치, 주변 환경의 조화를 고려하지 않은 사인들, 전체 공원 안내사인 디자인의 일관성 부족 등 공적공원의 특성을 제대로 살리지 못하는 문제를 중심으로 사인디자인 방안을 제안한다. 이를 위해서 국내외의 대표적인 공공원과 사공원을 분석하여 그 문제점을 도출한 후 사인의 종류를 분류하였으며 사인의 종류에 따른 디자인 가이드라인을 제안하였다. 나아가서 공원 방문객의 편리성 및 공원사인에 대한 사용성과 사인디자인에 관한 기대요소를 선정하여 평가함으로써 제안하는 디자인의 객관성을 입증하였다. 본 연구의 결과 각 공원의 특성에 따른 각 사인 체계의 사용성 및 사용자 요구도에 차이가 있음을 알 수 있었으며 이를 바탕으로 사용자의 기대치에 부응 할 수 있는 공적공원 및 사적공원이 나아가야할 사인체계의 디자인 방안을 제안하였다. The effects of 5day-work-week have given us strong family relationships by increasing sparing time. People who visit national parks enjoy the intimate with family. Especially, the public park has much benefits, such as people visit easily with moderate prices. This research is focused on the sign-design to increase watching effects with low price. However, there are some problems suck as assignments of sign without much considerations for moving line, unmatched with circumstances, lacking of consistency images. Thus, the effect of entertaining is decreased. For this, the paper analysis large-scale public park and large-scale private parks, and solves the several kinds of the problems. We also classify the types of sign designs and propose the sign design methods on characteristics. Therefore, we provide the objectivity of proposed sign designs by evaluating conveniences and expectations, and proposed the design methods of public parks and private parks.

        Objectives : Recently a lot of research is being done for find antidiabetic medicine which has no side effects. This study aimed to investigate the antidiabetic and antiobesity effects of Supungsunki-hwan partitioned prescriptions on obese type 2 diabetes mouse. Methods : Type 2 diabetes mellitus and obesity were induced by Surwit's high fat, high sucrose diet for 8 weeks. Mice were divided into 3 groups of ND (normal diet, n=10) HFD (high fat and high sucrose diet, n=10) and SPP (high fat and high sucrose diet with Supungsunki-hwan partitioned prescriptions, n=10) groups. Body weights were measured every week. After 7 weeks, fasting blood sugar and oral glucose tolerance tests were conducted. After 8 weeks, blood samples of all mice were taken from their heart and analyzed biochemically. At the same time, epididymal fat pad and liver weights were measured. Histological size of white adipocyte were measured as well. Results : Compared with a HFD group, body weight, fructosamine, epididymal fat pad weight and white adipocyte size decreased. High-density lipoprotein cholesterol levels increased in the SPP group. Conclusions : These results suggest that SPP has antidiabetic and antiobesity effects in high fat, high sucrose diet induced obese mice.

        Anti-inflammatory activity of the extracts of Hibiscus manihot was investigated through the evaluation of its inhibitory effect on the production of inflammatory biomarkers (i-NOS, COX-2) in RAW264.7 murine macrophage cells. Among the sequential solvent fractions (hexane, dichloromethane, ethyl acetate, n-butanol and water), the fractions of dichloromethane (1 ${\mu}g/ml$) and ethyl acetate (5 ${\mu}g/ml$) showed potential inhibitory activities on i-NOS and COX-2 activity in RAW264.7 cells. These results suggest that Hibiscus manihot might have an anti-inflammatory activity through the suppression of inflammatory markers.

        적색 안료인 탄탈륨 질화물(Ta<sub>3</sub>N<sub>5</sub>)의 특성에 도핑 물질 및 최종질화물의 산소/질소 함량이 미치는 영향

        박은영,피재환,김유진,조우석,김경자,Park, Eun-Young,Pee, Jae-Hwan,Kim, Yoo-Jin,Cho, Woo-Seok,Kim, Kyeong-Ja 한국분말야금학회 2009 한국분말야금학회지 Vol.16 No.6

        Tantalum nitrides ($Ta_3N_5$) have been developed to substitute the Cd based pigments for non-toxic red pigment. Various doping elements were doped to reduce the amount of high price Tantalum element used and preserve the red color tonality. Doping elements were added in the synthesizing process of precursor of amorphous tantalum oxides and then Tantalum nitrides doped with various elements were obtained by ammonolysis process. The average particle size of final nitrides with secondary phases was larger than the nitride without the secondary phases. Also secondary phases reduced the red color tonality of final products. On the other hand, final nitrides without secondary phase had orthorhombic crystal system and presented good red color. In other words, in the case of nitrides without secondary phases, doping elements made a solid solution of tantalum nitride. In this context, doping process controlled the ionic state of nitrides and the amount of oxygen/nitrogen in final nitrides affected the color tonality.

        탄탈륨 질화물(Ta<sub>3</sub>N<sub>5</sub>)의 적색도 향상에 미치는 NH<sub>4</sub>Cl의 영향

        박은영,피재환,김유진,조우석,Park, Eun-Young,Pee, Jae-Hwan,Kim, Yoo-Jin,Cho, Woo-Seok 한국세라믹학회 2009 한국세라믹학회지 Vol.46 No.6

        The Tantalum nitride has attracted wide at attention as issues related to the toxicity of Cd-related materials. But in the titration process of Ta$Cl_5$ solution with $NH_4$OH, $NH_4$Cl, as a by product, was remained in the prepared Tantalum precursor. The tantalum precursor with $NH_4$Cl was nitrided by ammonolysis. The red color tone of $Ta_3N_5$ was reduced by the residual $NH_4$Cl reduce. Therefore, amorphous Tantalum precursor was prepared by filtering process with as hydrous ethanol to remove the $NH_4$Cl. In the case of using Tantalum precursor without $NH_4$Cl, we successfully synthesized the Tantalum nitride with good red color. The value of red color tone was improved from $a^*$=36.8 to $a^*$=53.0. The synthesized powder was characterized by XRD, SEM, the Nitrogen / Oxygen Determinator, TG-DTA, and the CIE $L^*a^*b^*$ colorimeter.

        Microstrip Square Open Loop Resonator를 이용한 저위상 잡음 발진기에 관한 연구

        박은영,서철헌,Park Eun-Young,Seo Chulhun 한국전자파학회 2006 한국전자파학회논문지 Vol.17 No.1

        본 논문에서는 발진기의 위상 잡음 특성을 개선시키기 위하여 개방형 루프 구조를 공진기에 적용하였다. 개방형 루프 공진기는 크기 면에서 훨씬 소형화될 뿐만 아니라 협대역과 예리한 선택도를 갖기 때문에 이러한 특성을 이용하여 저 위상 잡음 발진기에 대한 연구를 수행하였다. 개방형 루프 구조를 이용한 공진기는 결합 계수를 증가시켜 Q값을 높여 주어 결과적으로 발진기의 위상 잡음 특성을 향상시킬 수 있다. 본 논문에서 제안된 발진기는 5.84 GHz에서 발진이 일어났으며, 출력은 -0.5 dBm, 하모닉 특성은 -15.83 dBc, 위상 잡음 특성은 100 kHz offset에서 -111.17 dBc/Hz이었다. 이를 통하여 개방형 루프공진기 구조를 이용한 발진기는 기존의 공진기를 이용한 발진기에 비해 100 kHz offset에서 15 dB 개선을 보였다. This paper has presented a low phase noise oscillator using a square open loop with microstrip structure. A square open loop resonator has a large coupling coefficient value, which makes a high Q value, and has reduced phase noise. This oscillator has presented the oscillation frequency of 5.84 GHz, harmonics of -15.83 dBc and the phase noise of -111.17 dBc/Hz at the offset frequency of 100 kHz. In conclusion, the proposal structure has improved phase noise of 15 dB at the offset frequency of 100 kHz compared with the conventional structure of oscillator.

      • 보건행정 전공 대학생들의 병원실습 만족도에 영향을 미치는 요인분석

        박은영,장영진,홍종필,Park, Eun-Young,Jang, Young-Jin,Hong, Jong-Pil 한국임상보건과학회 2017 한국임상보건과학회지 Vol.5 No.1

        Purpose .This study aims to assess the influence factors on the level of satisfaction with hospital training and to provide basic data for more efficient hospital practice of students' public health administration . Methods . We have conducted a survey on students satisfaction with their hands on practice against 200 students in Busan, Kyeongnam and Kyungbook area, who have completed their practice in public health administration. We have identified the general characteristics of the target respondents, the current training status of the department for the hospital practice and training venue; also analyzed the characteristics composed of the apprentice student's attitude before the practice, satisfaction with the department training program and hospital for practice, as well as their practice at hospital. The general characteristics of the target respondents and clinic practice status at the hospital were measured in percentage and frequency analysis; the average and standard deviations of hospital size were also measured; and the correlations between satisfaction with the department, attitude towards the practice and satisfaction with the hospital were analyzed. Results . Most public health administration students experienced their practice at the hospital after the first semester on the $2^{nd}$year and they have received the foundation training for the practice. The survey allowed multiple responses and the results are as follows: medical terminology 49.5%, medical coordinator 36.7%, Hospital administration 26.5%, Health insurance 17.3%, and medical recording and practice 13.8% respectively. In terms of each individual student's attitude towards the practice at the hospital, the respondents answered as follows: I have completed the obligatory subjects for the practice before the practice 89.5%; I have been fully informed on the hospital for my practice. 74.5%; I responsibly practiced and worked with professionalism and sense of belonging to the hospital as a member of staff 90%; I have actively learned and adopted 95%; My knowledge and skills from the practice was relevant to the theory and practice from my course 83.5%. The findings of satisfaction by size of hospital were in order of a small clinic($3.24{\pm}0.63$), medium sized clinic($3.27{\pm}0.65$), hospital ($3.20{\pm}0.61$), and large sized comprehensive hospital ($2.93{\pm}0.74$). Consequently the satisfaction rate shows no significant difference by size of hospital. In relations between practice attitude and satisfaction with subject, the matter of acquiring information and fully understanding of the hospital for practice before practice(p=0.04), the matter of a sense of belonging and responsibility at hospital during practice(p=0.33). the matter of active adaptation attitude during practice (p=0.42), and the matter of correlations with school curriculum during practice(p=0.00) showed significant results. In relations between practice attitude and satisfaction with the hospital for practice, the matter of acquiring information and fully understanding of the hospital for practice before practice(p=0.01), the matter of a sense of belonging and responsibility at hospital during practice(p=0.04), and the matter of correlations with school curriculum during practice(p=0.00) showed significant results. Conclusion . The most essential subject for the practice in public health administration is medical terminology and there is no significance in satisfaction with the practice by size of hospital. Students were content with the hospital where they can experience as much as possible. Students content with their major show positive attitude towards the practice and so do those content with the hospital. Those with the positive attitude towards the practice show the high correlation of satisfaction with both the major and hospital. As a result, the satisfaction with the major is the significant attribute to the practice

        학동기 아동에서의 가와사끼병의 임상 특징

        박은영,김지혜,김혜순,손세정,Park, Eun Young,Kim, Ji Hye,Kim, Hae Soon,Shon, Sejung 대한소아청소년과학회 2007 Clinical and Experimental Pediatrics (CEP) Vol.50 No.3

        Purpose : Kawasaki disease (KD) rarely occurs in school-aged children. We clarified the characteristics of KD in this age group to provide tips for a high index of suspicion. Methods : Features of 38 patients with KD who were 7 years of age or older were retrospectively reviewed. Results : The incidence of the KD patients ${\geq}7years$ was 4.9 percent. The ratio of male to female was 2.5:1. Of the 38 patients, nine patients (24.0 percent) were diagnosed with typical KD and 29 patients (76.0 percent) with incomplete KD. In incomplete KD patients, cervical lymphadenopathy (69.0 percent) occurred most frequently, followed by conjunctival injection (62.0 percent) and polymorphous rash (45.0 percent). These patients occasionally presented with other additional symptoms including abdominal pain, headache, vomiting and arthralgia. Incomplete KD was initially diagnosed as cervical lymphadenitis (34.0 percent), viral infection (14.0 percent), scarlet fever (7.0 percent), meningitis (7.0 percent), and Kikuchi disease (7.0 percent). Coronary complications were noted in 15 patients (39.0 percent). Of the 37 patients treated with intravenous immunoglobulin, five (14.0 percent) were resistant to the therapy and all had coronary abnormalities. Conclusion : Most patients with KD ${\geq}7years$ of age have incomplete presentations. They tend to have a higher incidence of initial presentations of unilateral neck mass and coronary artery involvement. In school-aged children, fever and cervical lymphadenitis or suspected neck infection unresponsive to intravenous antibiotics should signal the possibility of KD. A high index of suspicion and prompt treatment is essential in this age group of patients. 목 적 : 학동기 아동에서의 가와사끼병은 드물게 나타나며 대부분 불완전한 양상을 보이므로 진단이 늦어지고 심혈관계 합병증의 발생이 증가한다. 본 연구에서는 이들의 임상 특징을 조사하여 이 연령군에서 가와사끼병의 조기 진단에 도움이 되고자 하였다. 방 법 : 1995년 6월부터 2006년 5월까지 가와사끼병으로 입원하여 치료받은 7세 이상의 소아 38명을 대상으로 임상 특징을 후향적으로 조사하였다. 결 과 : 연구 기간 중 7세 이상의 환아는 4.9%이었고, 남녀 비는 2.5:1이었고, 연령 분포는 7-12세였다. 76%가 불완전형 가와사끼병으로 이 때에는 발열을 제외하고 경부 림프절 비대가 가장 흔히 나타났고(69%), 다음으로 양측성 결막 충혈(62%), 부정형 발진(45%)의 순이었다. 또한 복통, 두통, 구토 및 관절통 등 다른 증상을 동반하는 경우가 있었다. 불완전형 가와사끼병의 초기 진단명은 경부 림프절염이 10명(34%)으로 가장 많았고, 그 외에 바이러스 감염 4명(14%), 성홍열 2명(7%), 뇌수막염 2명(7 %), Kikuchi 병(Kikuchi disease) 2명(7%)의 순이었다. 관상동맥 합병증은 15명(39%)에서 나타났고, 첫번째 IVIG 치료에 반응하지 않은 경우는 5명(14%)이었으며 이들에서 모두 관상동맥 병변이 발생하였다. 결 론 : 학동기 아동의 가와사끼병은 대부분 불완전형으로, 경부 림프절 비대가 흔하게 나타나며 심혈관계 합병증의 발생률이 높고 비특이적인 증상들을 동반하는 경우가 많아 다른 감염성 질환으로 오진되기 쉽다. 따라서, 항생제 치료에 반응하지 않고 발열이 지속될 경우 가와사끼병의 가능성을 항상 염두에 두어야 하며 조기 진단 및 치료를 함으로써 심혈관계 합병증의 위험성을 감소시켜야 한다.

        수돗물 불소화와 노령 인구의 고관절 골절에 대한 생태학적 연구

        박은영,황승식,김재용,조수헌,Park, Eun-Young,Hwang, Seung-Sik,Kim, Jai-Yong,Cho, Soo-Hun 대한예방의학회 2008 Journal of Preventive Medicine and Public Health Vol.41 No.3

        Objectives : Fluoridation of drinking water is known to decrease dental caries, particularly in children. However, the effects of fluoridated water on bone over several decades are still in controversy. To assess the risk of hip fracture related to water fluoridation, we evaluated the hip fracture-related hospitalizations of the elderly between a fluoridated city and non-fluoridated cities in Korea. Methods : Cheongju as a fluoridated area and Chungju, Chuncheon, Suwon, Wonju as non-fluoridated areas were chosen for the study. We established a database of hip fracture hospitalization episode based on the claims data submitted to the Health Insurance Review Agency from January 1995 to December 2002. The hip fracture hospitalization episodes that satisfied the conditions were those that occurred in patients over 65 years old, the injuries had a hip fracture code (ICD-9 820, ICD-10 S72) and the patients were hospitalized for at least 7days. A total of 80,558 cases of hip fracture hospitalization episodes were analyzed. Results : The admission rates for hip fracture increased with the age of the men and women in both a fluoridated city and the non-fluoridated cities (p<0.01). The relative risk of hip fracture increased significantly both for men and women as their age increased. However, any difference in the hip fracture admission rates was not consistently observed between the fluoridated city and the non-fluoridated cities. Conclusions : We cannot conclude that fluoridation of drinking water increases the risk of hip fracture in the elderly.

        조밀한 층을 포함하는 사질 지반의 지지력에 관한 연구

        박은영,이상덕,권오엽,허창택,Park, Eun Young,Lee, Sang Duk,Kwon, Oh Yeoh,Hu, Chang Tack 대한토목학회 1993 대한토목학회논문집 Vol.13 No.2

        기초 지반이 몇개의 토층으로 구성된 경우 그 지지력은 각 토층의 강성도와 두께 및 위치 등에 의해 영향을 받는다. 따라서 기초 설계시에 기초의 지지력을 정확히 구하고 파괴면을 예측하기 위해서는 토층의 상태를 지지력 계산에 고려해야 한다. 본 연구에서는 기초 지반이 사질지반이고 중간에 상대적으로 조밀한 지층을 포함하는 경우에 조밀한 층의 두께나 위치가 기초의 지지력 및 파괴모양에 미치는 영향을 극한 해석의 상한한계(upper bound)쪽에서 완전해에 가까운 해를 구하는 K.E.M(Kinematical Element Method)을 이용하여 검토 하였으며, 기초 폭(B)의 3/5 B보다 깊지 않은곳에 조밀한 층이 위치하는 경우에는 기초의 지지력 과 파괴모양이 조밀한 층의 영향을 받는 것으로 나타났다. The bearing capacity of the sand foundation including a thin dense sand layer depends on the stiffiness, thickness and the location of the dense sand layer. In this paper was the influence of the dense sand layer on both the bearing capacity and the failure configuration is studied by means of K.E.M(Kinematic Element Method). K.E.M was implemented to get the excat solution starting from the upper bound of the analysis. The result show that the bearing capacity of the foundation and the failure configuration is greatly influenced by the dense sand layer, when the layer is located not deeper than 3/5 of the foundation width.
